"Parkerizing" on WWII electric torpedoes





2003

Dear readers:

I am trying to obtain information regarding the "painted" finish of the U.S. Navy's WWII MK18 electric torpedo, which was manufactured by the Westinghouse Corp. at Sharon, PA in mid-1943. While attending the Navy's torpedo school in Newport, RI, we were told by the instructor that the inner and outer shell of the torpedo was Parkerized. This glossy coating had a slightly greenish-yellow and very durable finish. This coating was used on a subsequent torpedo, the MK 27 and Mods. well into the late 1950s. What I need is verification that the "Pakerizing" process was used on these torpedoes, so I can include this info in a booklet that I'm working on, describing the types and specifications of pre and post-war U.S. Navy torpedoes.

Thanking you in advance,

True the inner and exterior of the tubes were phosphated (parkerized) but the exterior was also painted to prevent corrosion. The exterior paints vary as to colour but what you are describing sounds like a zinc chromate primer which is a greenish yellow over phosphate.

The newspaper article at the link below (Pittsburgh Gazette, October 1945) states "parkerizing" was used on a torpedo developed by Westinghouse Electric:

My dad told me 60 years ago that a torpedo was tested in Lake Julia, Sharon, Pa. close to Westinghouse, Recently they started dredging the lake and I informed them there was a torpedo on the bottom and they did find it. I will attach a photo. Contact me for more info. if you have interest.
